Let w = liters of water needed
4.70= acid in 40% solution 

4.70/70+w  = .28

28=.28.(70+w)
70+w=100
w=30


30 liters of water is needed

Answer:

<em>B) Victor</em>

Step-by-step explanation:

<em>A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The </em>

<em>closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| = </em>

<em>0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is</em><em> B) Victor!</em>
